Brief description of the drawings
Below in conjunction with accompanying drawings and embodiments, the invention will be further described, in attached drawing：
Fig. 1 is the partial sectional view of pipeline in the present invention；
Fig. 2 is the A portions enlarged drawing of Fig. 1.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, with reference to the accompanying drawings and embodiments, it is right
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
Fig. 1 is the partial sectional view of pipeline in the present invention；Fig. 2 is the A portions enlarged drawing of Fig. 1.As depicted in figs. 1 and 2, this hair
Bright pipeline 100 includes at least the first duct section 101 being connected with each other and second pipe section 102, and two are illustrate only in figure
Duct section, but may include more than two duct sections in other embodiments.The internal diameter of each duct section 101,102 is identical, can
To be plastic conduit or be the compound pipeline complex pipeline for accompanying steel band, but the inner surface of each duct section is plastic interior surfaces.
The inner surface of the adjacent end portion of first, second duct section 101,102 is collectively forming join domain 103.In order to avoid
The influence of temperature, between the adjacent end portion of first, second duct section 101,102, reserves the flexible gap not less than 30mm.Pipe
Road 100 is further included is bonded in the inner surface of first, second duct section 101,102, so as to by two duct sections by foamed glue 104
101st, 102 PE to link together（Polyethylene）Connect band 105.The PE connect bands 105 are perpendicular to the axial cross section of pipeline 100
For annular.According to the caliber of pipeline 100, the PE connect bands 105 of different dimensions can be selected.In bonding, first first,
Second pipe section 101, the join domain 103 of 102 inner surfaces spray foamed glue 104, and PE connect bands 105 are held round and are fitted in afterwards
It is sprayed with the inner surface of foamed glue 104.
Pipeline 100 is further included for aiding in PE connect bands 105 being fixed to first, second duct section 101,102 inner walls
Connector 106, which can be tapping screw, its quantity is multiple, to be equidistantly arranged in PE connect bands 105
On.
Since pipeline 100 is usually used in conveying the liquid such as drinking water, these liquid inevitably from pipeline 100 from inside to outside
Infiltration.When liquid infiltrates into foamed glue 104 for example, by the gap between connector 106 and PE connect bands 105, foamed glue
104 meeting water swellings, are sufficient filling with gap, so as to strengthen the water resistance of pipeline 100.
Between the both ends of PE connect bands 105 and first, second duct section 101,102 inner surfaces, it is understood that there may be small
Gap, in order to strengthen waterproof, the both ends of PE connect bands 105 respectively by PE solders 107 be welded on first, second duct section 101,
102 inner surface.
Illustrate the connection method of the pipeline 100 of the present invention below.The connection method mainly includes the following steps that：
Inspection before S0, connection, first checks whether the tubing surfaces externally and internally of first, second duct section 101,102 is smooth, has
Without it is damaged, have no concave-convex or the steel band exposed（Compound pipeline complex pipeline for accompanying steel band）If there is steel band exposed, prevent that steel band is naked
Whether repair welding is smooth for the PE solders of dew.Debris in first, second duct section 101,102 is purged, cleaning first, second
The pipe end join domain of duct section 101,102；
S1, align the pipe end of first, second duct section 101,102, makes both axis straight and is located at same straight line
On, and reserve the flexible gap not less than 30mm.
S2, the inner surface mark foamed glue spray regime terminated line in first, second duct section 101,102, the foamed glue
Spray regime is smaller 15-20mm than the lay length of actual PE connect bands 105 to be advisable, with it is reserved follow-up to PE connect bands 105 into
The welding job area of row welding.Afterwards, foamed glue 104 is circumferentially equably injected in the foam gun being cleaned
By first, second duct section 101, the join domain of 102 inner surfaces, spray regime must not exceed the termination of foamed glue spray regime
Line., can be as needed during practice of construction, the flow control valve of foam gun is adjusted, so as to adjust the colloid stream of foamed glue
Amount.
S3, using supporting equipment PE connect bands 105 are held round and pressed, be fitted in it and sprayed foamed glue 104
The join domain 103 of first, second duct section 101,102 inner surfaces, the inner surface of PE connect bands 105 is tapped using rubber hammer,
Percussion dynamics appropriateness, ensures that PE connect bands 105 are uniformly bonded with foamed glue 104, so that by first, second duct section 101,102
Link together.The operation bonding with foamed glue 104 of PE connect bands 105 was completed within 20 minutes, to avoid 104 table of foamed glue
It can not be bonded after the drying of face.
S4, with predetermined spacing, PE connect bands 105 are circumferentially locked using connector 106 and are fixed on
First, second pipe section 101,102 inner surfaces.It is self tapping spiral shell in connector 106 to improve speed of application and reduce labor intensity
In the case of nail, the operation instruments such as electric screwdriver or fixed batch, square pneumatic screwdriver can be used to tighten tapping screw.Due to first, second pipeline
101,102 inner surfaces of section be frosting, PE connect bands 105 are PE materials, and the gear of operation instrument, which controls, to be preferably controlled in
Low grade, using 1.5-1.6Nm as initial value, then gradually the moment of torsion of adjusting screw is to desired value, to prevent first, second pipe
Road section 101,102 or PE connect bands 105 crack and connector 106 slides tooth.
S5, with miniature extruder or EVA welding guns, use end and first, second pipe of the PE solders to PE connect bands 105
Road section 101,102 inner wall junctions carry out circumference soldering and sealing sealing.Complete the connection of first, second duct section 101,102.
Compared with prior art, dedicated energized equipment is not required in pipeline 100 of the invention, and it is heavy to eliminate carrying etc.
Work, the connection between each duct section is very convenient, easy to operate, and obtained pipeline 100 has good sealing water resistance.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
